摘要： A touch sensing apparatus includes a coordinate calculator configured to count a current number of touches and calculate an estimated number of touches, by the unit of touch group, by using touch data including touch coordinates of a plurality of touch electrodes, and detect a discontinuous touch corresponding to a touch group in which the current number of touches and the estimated number of touches are not the same; and a touch data generator configured to generate the touch data including corrected coordinate data.

摘要： A touch sensing apparatus tracking a curve includes an interpolation coordinate generator configured to sense a first touch point, a second touch point and a third touch point, and calculate an interpolation point between the second touch point and the third touch point, wherein the curve is formed by the first touch point, the second touch point, the third touch point and the interpolation point, and the interpolation point is determined by the first touch point, the second touch point and the third touch point.
